The concrete pipe pile comprises a first pipe pile body and a second pipe pile body, the first pipe pile body comprises an upper connecting base, when a transverse rod moves downwards, the transverse rod enables air at the bottom of a piston plate to enter a connecting groove for circulation, the air flows to an air outlet through the connecting groove, and the air outlet is communicated with the second pipe pile body. Air enters the lower portion of the supporting plate through the space between the two sets of fixing blocks, negative pressure is formed, the descending speed of the supporting plate is reduced, before the pipe piles are settled and poured at the same time, the fixing sleeve is arranged in a foundation in advance, during pouring, the first pipe pile is put down through the fixing sleeve, and pouring is conducted in the first pipe pile in the descending process of the first pipe pile; when the outer wall of the corrugated connecting sleeve moves to the position of the fixing sleeve, the inner wall of the fixing sleeve enables the corrugated connecting sleeve to be continuously and slightly deformed and reset, meanwhile, vibration of the whole corrugated connecting sleeve can be improved, the supporting plate and concrete on the supporting plate are in a wriggle-like state, bubbles in the concrete are reduced in the vibration process, and the concrete is evenly distributed.
本发明公开了一种采用边沉降边浇筑的混凝土管桩，包括第一管桩和第二管桩，第一管桩包括上连接座，在横杆向下移动时，横杆使得活塞板底部的空气进入连接槽内进行流通，空气经连接槽流通至出气口处，空气经两组固定块之间进入托板的下方，形成负压，减慢托板的下行速度，在对管桩进行边沉降边浇筑前，固定套预设于地基中，浇筑时，将第一管桩经固定套内放下，在第一管桩下降过程中对第一管桩内进行浇筑，在波纹连接套的外壁行至固定套处时，固定套的内壁使得波纹连接套不断轻微形变及复位，同时波纹连接套整体会提高震动，使得托板及其上的混凝土呈现类似于蠕动的状态，在震动中混凝土中的气泡减少，使得混凝土分布均匀。
